HINGE-LOCK ieaaeaa.

Application filed February 20, 1917/ Serial No. 149,764.

To all whom z't may concern:

Be it known that I, VILLIAM A. HEN- DnRsoN, a citizen of the UnitedS'tates, and

resident of Larchmont, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Hinge-Locks, of which the following is a specification.

This invention relates to locking hinges and is especially adapted for use where articles are to be folded or collapsed, the object of the invention being to hinge two parts of a frame or other structure together and to provide a latch to be operated by a screw and acting on an inclined surface to firmly unite and brace the two parts together or to quickly release them, the parts being so let into the woodwork of the structure as to be almost invisible and precludes the chances of hooking and catching articles of clothing while in its various positions.

These and other objects and details of the invention are more fully described in the'following specification, set forth in the appended claims and illustrated in the accompanying drawings, wherein:

Figure l is an enlarged sectional view through two sections of a door showing the lock in operation.

Fig. 2 is a similar view with the upper section of the door folded down.

Fig. 3 is a front elevation of the hinge.

Fig. 4 is a sectional view of Fig. 1.

When a hinge of this nature and as here'- in described is applied to the door of an automobile its lower member consists of a plate 10 secured to the inside of the. door and made flush with the surface thereof and having a knuckle 11 at its upper end. A lateral plate 12 is let into the upper horizontal surface of the door 13 and has a slot 14 near its outer end while a cavity 15 is cut in the door beneath the same. Both of the plates 10 and 12 are rigidly secured to the door by screws or otherwise and the eye 11 is provided with a pintle 16 on which is pivoted the upper hinge member and which consists of the horizontal plate 17 and vertical plates 18 and 19 on the inside and outside respectively of the upper door section 20 and rigidly screwed and braced to the same so as to withstand the strain of the long leverage of any force put upon the upper end of the said door section.

Specification of Letters Patent.

lPatented Dec. 41, 1917..

Swiveled in the plate 19 and loosely pass ing through the plate 18 is a screw21 with a head 22 of any desired shape for manipulation and on the inner side of the door, while carried by the screw and adapted to be moved in or out by the same is a yoke 23 retained in its vertical position by the walls of the recess 24 in the lower end of the door section 20.

In suitable bearings 25 on the plate 17 is pivoted a lever 26 whose lower end is a dog 27 adapted to enter the slot 14 which ha an inclined front end 28 on which the face of the dog is adapted to play, and the upper end of the lever 26 has a pin 29 passing through it and playing in the jaws 30 on each side of the yoke 23. When the screw 21 is turned by means of the head 22 the yoke 23 is moved along the same and swings the lever 26 on its pivot 31, either to lock the door sections 13 and 20 together, as shown in Fig. 1, or to release them as in Fig. 2 when one door section may be lowered.

When the sections occupy the latter po sition there are few or no obstructions to mar the finish of the car and little to indicate that the door is made of two pieces. The difliculty heretofore in the hinging and locking of the two door sections together. has been the liability of the parts to be broken by parties not familiar with the operation of the lock, or of parts of the device being lost or rattling on account of looseness.

The present lock will secure the two sec tions rigidly and substantially, and the inclined wearing surface of the face of the dog with the edge of its slot may be relied upon to always assure a tight joint and one permitting no rattling of the parts.

It is obvious that the parts may be other wise arranged or modified without departing from the essential features above described or from the scope of the appended claims.

What I claim is:

1. In a lock hinge, the combination with a rigid member having a socket, of a hinge member secured to the rigid member and having a perforated plate to fit around the socket, a second hinge member carrying a swinging member with a recess, a dog pivoted in the recess and having a hook adapted to extend into the socket and engage the edge of the perforated plate when the swinging member is closed on the rigid member, and a screw operated outside of the swinging member and adapted to swing V adapted to play through the horizontal plate to enter the slot, a pin in the upper end of the dog, a screw carried by the vertical plates of the second member, and a yoke on and actuated by the screw to straddle the pin on the dog and swing the latter.

Signed at New York, in the county of New York, and State of New York, this 15th day of February, A. D. 1917.
